I recently upgraded to 2.4. And now I cant upload images or files anymore.
When i click on the upload button i get " file is not a valid upload!"

I did search teh forum, and I found that more people than I had the same problem, but noone had found an answer for the problem.

So I hope someone can point me in the right direction. I do have some more sites I would like to upgrade to SS 2.4 but if there is no solution for the upload problem then SS 2.4 cant be a stable release in my opinion. Should I wait for SS 2.4.1?

HanSolo, did u eventually solve your problem ?
I now upgraded my client to 2.4.1 and have an upload problem - admin can upload, user can't upload.
do you have swfupload installed ?

Had the same problem on one hosting.

Everything works fine on my computer and another hostings just one had such problem.
"Files and Images" works fine, but when i was clicking "add image" in TinyMCE and Upload then, i got that error.

It was fixed after I modified sapphire/filesystem/Upload.php function validate()

I just moved
$pathInfo = pathinfo($this->tmpFile['name']);
before
if(isset($this->tmpFile['tmp_name']) && !is_uploaded_file($this->tmpFile['tmp_name']) && !SapphireTest::is_running_test())

I tried to remove conditions to parse params, but got nothing ... it's very strange, but now it's working.

Tonyair:
tried to follow your suggestion. No change :(
When i click "add files to "Uploads" button, the lightbox comes up with the following error:

is this swfupload?

Tonyair: yes it is.
When adding uploadify, there's no change. If i remove swfupload and leave dom and uploadify only, i get an DOM error insisting on installing swfupload. This might change when UncleCheese brings uploadify support for dom ?

Maybe, but actually I use only DOM and swfupload, i can attach my swfupload version with the latest swfupload version and user side image resizing if u need

Please do, i will see if that helps.
